• b = 2 and 3

Solve by Square Root Property ( Hint isolate x²)

16a² - 9 = 0

• a = ^-3/₄, ³/₄

• a = ^-4/₃, ⁴/₃

• a = ^-9/₁₆, ⁹/₁₆

• a = ^-16/₉, ¹⁶/₉

Solve by factoring. (Hint-Set factors to zero and solve for x)

(x+3)(8x-11) = 0

• x = 3 or x = 1 3/8

• x = 3 or x = -1 3/8

• x = -3 or x = -1 1/8

• x = -3 or x = 1 1/8

Solve by taking square roots:
